'Application filed July 24, 1915.

.1 hall whom it may concern:

Be it known that I, i' irrnnn G. .BIMSON, a citizen of the United States of America, and resident of Berthoud, in the county of Larimer and State of Colorado, have invented certain new and useful Improven'le'nts in Beet-Harvesters, of which the following is a specification.

This invention relates to harvesters and particularly to beet extractors or harvesters.

An object of this invention is to produce beet lifters which engage opposite sides of the vegetable and dislpdge it from the ground, the said invention having for its further object the provision of novel means for regulating the depth of travel of the beet'engaging elements and for permitting the adjustment of the saidbeet engaging elements so that they will have a greater or less tendency to descend-underthe surface of the earth and increasing or diminishing the depth at which the vegetable is engaged.

A; still further object of this invention is to provide removablepoints which may be readily applied to or removed from the associate members of a beet harvester, it having been found in practice that the points become dull through protracted use and that they sometimes become impaired or broken. By reason of this invention, therefore, the points may be removedfor sharpening or for substitution and this has been found to be a comparatively expensive means in the upkeep of implements of this character. 7

lVith the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification wherein like characters denote corresponding parts in the several views, and in which Figure 1 illustrates a perspective View of a horse drawn beet harvester, embodying the invention; Fig. 2 illustrates a detail view of a fragment of an extracting bar with the adjustable extensions applied thereto; Fig. 3 illustrates a view similar to Fig. 2 with the parts in different positions of adjustment; and Figs. 4 and 5 illustrate sectional views respectively of the devices shown in Figs. 2 and 3.

tive view of the rear point 19.

In these drawings 6 denotes a frame, the handles and 8 the draft rigging, all of which is of any ordinary construction and is not described in detail.

The standards 9 are secured to the frame and their lower ends are supplied with extracting bars 10, the purposes of which are well known. In the present invention, the forward ends of the extracting bars are provided with adjustable and removable bars and theircorrelated parts are of dupli cate construction, and a description of one will sufiice as a disclosure of the pairs which are utilized in the implement.

- It is apparent from an inspection of the drawing that the forward end of each extracting bar has a beveled upper edge 11 end of removable whereas the'lower edge 12 is on the plane of I themain portion of the bar. There is a transversely disposed aperture 13 in the said bar for the reception of a pin or bolt 14: by which the sleeve 15 is held on the bar. The sleeve has a socket 16, the upper and lower walls of which taper from the rear end and it is the purpose of the inventor that the socket shall be of such size as to receive the end of the extracting bar. Furthermore the relation of the edges of the extracting bar and the walls of the socket is such that the sleeve may he inverted on the extracting bar and that regardless of the position of the said sleeve on the extracting bar, the edges of the extracting bar will be in engagement with the said sleeve and bar and that according to the position of adjustment of the sleeve on the bar, a greater or less pitch is afiorded and this of course will affect the direction of travel of the beet engaging members. lhe fact that the sleeve may be inverted and with the walls of the socket contacting the upper and lower edges of the extracting bar, insures a strong and durable joint and relieves the securing pin or member of undue strain.

The outer end of each sleeve is further provided with an inwardly tapered socket 17 which receives a tapered shank 18 of the removable point 19. The sleeve has an aperture 20 near its outer end and the shank 18 a securing bolt or pin 22 for holding the point in operative relation to the sleeve. One surface of the point is straight as shown at 23 and the opposite surface is beveled as shown at 24:

and as the point may be applied to the socket with either the surface 23 .or 24: at the bottom, the point and the sleeve may be so assembled as to cause the beet engaging members to have a tendency to descend in the earth and this will insure proper engagement of the members with the said furthermore those surfaces of the point and sleeve which are uppermost will gradually dislodge the beets as they are drawn under it. Aside from the fact that the surfaces of the joint are of the construction indicated for regulating the depth of travel of the point, the surfaces of the shank 18 which enter the socket 17 are at different angles from the horizontal so that according to the position of the shank inthe socket, the point may be given a greater or less pitch.

By the several adjustments described, the beet extracting members may be set to give the best results under working conditions,

which working conditions are affected bythe condition of the soil, the size .of the beets, etc. i

I claim 7 1. In a beet harvester, a frame, standards thereon, extracting bars secured to the stand-V ards, said extracting bars having beveled upper edges'at the front end forming'tapered extensions, sleeves having sockets with upper and lower walls at different angles, said sockets being adapted to receive the ends of the extracting bars and to fit the upperand lower surfaces thereof, said sleeves having tapered sockets in their front ends, and points having shanks fitted to the last mentioned sockets.
